Mars 2022-2023

These images were taken with a C14  on an AP900GTO mount.  I used a QHY290M and a QHY462C camera.  A Starlight Xpress USB  filter wheel was used to produce an RGB image.  I used an Astrophysics Advanced Barcon (starting April 23) working at 3X.    To capture I used  FireCapture 2.6.  For processing, I use AutoStakkert and  Registax V5 .

Seeing was very unstable today.  These images show Sinus Sabaeus and Sinus Meridiani.  Syrtis Major is moving east now and should be more visible in the coming days.  There are clouds over Mare Acidalium on the upper left.  Part of the polar cap is visible now.  There is some thin clouds over the Hellas Basin.


January 16, 2023


Condition was good this evening.

Sinus Sabaeus and Sinus Meridiani is at the CM.  Mare Erythraeum and Pyrrhea Regio is on the left.  Note the clouds on Mare Acidalium close to the north pole.  The north polar cap is visible.  Syrtis Major is setting on the right.  Hellas Basin is on the lower right and is covered with clouds.

Condition here had been terrible because of monsoon.  These are my first images of Mars this year.  Seeing was good today.

Mars is getting smaller as it moves away from us.  Sinus Sabaeus and Sinus Meridani are the prominent features in these images.  Oxia Palus and Niliacus Lacus is on the upper left.  Syrtis Major is setting on the right edge.  Hellas can be seen on the lower right with some thin clouds over it.  There is still some left over North Polar Hood and parts of the north polar cap (bright region) can be seen.


December 29, 2022


After a week of horrible weather we finally had a clearing.  Seeing was good but my imaging run was cut short when it became overcast!

Note the clouds over the Tharsis volcanoes.  The clouds of Mons Arsia is bigger.   The north pole is still covered a thinning polar hood.  Clouds are forming on the south pole.  There are clouds also on the southern temperate area.  This is obvious in the UV image.  Elysium can be seen on the upper left.  Olympus Mons can also be seen.



December 22, 2022


Weather here had been horrible.  I had a very brief clearing before the sky was overcast again.  Seeing was not great.

It's very cloudy in Mars.  The north polar hood is still there but clearing in some parts.  There are clouds over Hellas and the northern part of Syrtis Major.  Sinus Gomer is well resolved.  Elysium is on the upper right.


December 16, 2022


We had an early thunderstorm today.  But condition was great when I imaged Mars.  Seeing was very good.

Syrtis Major is the prominent feature here.  Sinus Sabaeus is on the left.   Hellas is to the South.  There are some clouds over Hellespontos and Deucaliones Regio.  The north polar hood is clearing up and we can now see parts of the north polar cap.


December 13, 2022


I missed the Mars Opposition this year due to bad weather here.  I finally had a clearing.  These images were taken using the QHY5III200M.

Sinus Sabeaus is in the CM.  Syrtis Major is setting on the right.  Hellas is clear of clouds in the north.  Mare Erythraeum is rising on the left.  Note the bright morning cloud on the lower left which is over Noachis.  The north polar hood has really cleared up.  The north polar cap can now be seen.


December 5, 2022


It was cloudy all day.  But it cleared up around 10pm just in time to image Mars.  Seeing was excellent.

These images show the region of Mare Erythraeum and Chryse.  Solis Lacus is on the lower left.  Sinus Meridiani is setting on the right.  The north polar hood is breaking up.  Is that the polar cap above the dark clearing?


December 3, 2022


I had a short clearing today. 

Solis Lacus is in the lower left.  Olympus Mons can be seen at the terminator on the upper left.  Mare Erythraeum, Aurorae Sinus and Chryse well resolved.  The albedo is a bit light probably because of dust?


December 2, 2022


We have been having terrible weather here.  In fact, it rained hard early this evening.  Fortunately, the sky cleared in time for Mars.  We are less than a week before opposition. Seeing was variable today.

Solis Lacus is prominent at the CM.  Olympus Mons is the bright spot on the upper left.   Of the three Tharsis Volcanoes, only Acreaus Mons is prominent. Phryxi Regio, Aurorae Sinus and Chryse can be seen on the left.


November 27, 2022


Condition was a bit unstable today.

Solis Lacus is prominent in these images.  Olympus Mons is on the upper left.  Tharsis dominates the center.  The north polar hood is thinning out.


November 26, 2022


After imaging Jupiter today, we had a heavy downpour.  Fortunately, it only lasted for a few minutes and the sky cleared again.  Seeing was good.

This region shows Olympus Mons and the 3 gaint Tharsis volcanoes (Mons Ascreaus, Pavonis and Arsia).  Solis Lacus can be seen on the lower right.  Mare Sirenum can be seen below and  Elysium is on the upper left.  The north polar hood is shrinking.  We should see the north polar cap soon.


November 24, 2022


Seeing was very good but I had to deal with passing clouds which was frustrating at times.

This region shows Mare Sirenum.  Solis Lacus is setting on the lower right edge.  Olympus Mons can be seen on the upper right.  Elysium on the upper left just below the north polar hood.


November 22, 2022


Conditions were perfect today. 

These images show the region of Mare Cimmerium.  Elysium can be seen just below the north polar hood.  Sinus Gomer can be seeing sticking out on the left.   The bright oval spot close to the right edge is Olympus Mons.  There seems to be some dust on the south with the clouds.


November 5, 2022


Condition was excellent today.  Here are some images of Mars.  The first was captured using a QHY290 mono camera.  The second was with a QHY462C color camera.  And the last image was taken though an IR850 filter.

These images show Sinus Meridiani/Sabeaus.  Chryse is on the left.  Mare Erythraeum is on the south side. 


April 23, 2022


I finally had a chance to image Mars! Mars is tiny now at only 5.6". Seeing was average but transparency was poor due to clouds. Mars was only 35 degrees above the horizon when I took this image.
This image shows the Tharsis volcanic region. Mars is too small to resolve Olympus Mons. Note the late afternoon clouds over the trio Tharis volcanoes. The south polar cap is huge.
